Benign carcinoid tumor of the large intestine, unsp portion

This code signifies a non-cancerous neuroendocrine tumor originating in the large intestine, where the specific segment of the large intestine (e.g., cecum, ascending colon, transverse colon, descending colon, sigmoid colon, rectum) is not documented. Carcinoid tumors are typically slow-growing and arise from enterochromaffin cells.

Use this code when diagnostic imaging, endoscopy, or pathology reports confirm a benign carcinoid tumor within the large intestine, but the precise anatomical location within the large intestine is not specified. This code is appropriate when the physician's documentation explicitly states "large intestine, unspecified portion" or similar ambiguous phrasing regarding the exact site.

• Do not use this code if the specific segment of the large intestine (e.g., cecum, rectum) is documented; instead, use a more specific D3A.02x code.
• Confirm the benign nature of the tumor; if malignant, a C7A.02x code would be appropriate.
• Ensure documentation clearly indicates "unspecified portion" of the large intestine to support this code.
